Banjo/11177 5. Wilson BY @unw WW ZYMz 3,093,224 Patented June II, 1963 ice The present invention generally relates to a window construction of the double hung type in which each sash is provided with a metal frame and the window itself includes a metal frame and track assembly for slidingly guiding the upper and lower sashes with the window construction also incorporating a storm window and screen assembly thereby providing a complete Window unit ready for installation in the window opening of a wall.

The primary object of the present invention is to provide a metal window construction of the double hung type incorporating a novel track arrangement which may be adjustable to vary the frictional resistance of sliding of the panes of glass in each sash.

Another object of the present invention is to provide a metal window construction in which each glass pane is provided with a frame removable from the sash frame and pivotally attached thereto whereby the glass panes may be removed from the sash frames or swung inwardly therefrom for ease of cleaning thereby enabling both sides of the panes of glass in the sash frames to be cleaned from inside of the building and also enabling the storm window sash panes to be cleaned from the inside of the building without risking possible injury from a fall such as could occur if it was necessary to lean outside of the building to clean the windows.

Still another object of the present invention is to provide a metal window construction of the double hung type in which a novel cam type lock is employed to lock the double hung sashes in closed position.

A further object of the present invention is to provide a window construction of the character described in which the lower inside glass pane may be pivoted about a horizontal axis at the lower edge of the sash frame or alternately about a vertical axis at one edge thereof.

A still further object of the present invention is to provide a window construction in which each glass pane may be easily converted to a double pane window construction with the area between the panes forming a dead air insulation space.

Yet another important feature of the present invention includes an arrangement for storage of one panel of the storm window or screen with there being a novel lock means for retaining the panels within their respective frames. v

Yet another important feature of the present invention is to provide a metal Window construction in which the corners of the window frame are interconnected by corner angle members and the hollow metal construction of the window frame may be filled with insulation material and the window frame assemblies may be attached to each other in side by side relationship to provide a multiple window unit in which each of the window panes or panels are removable from the inside to facilitate cleaning, repair and the like.

Other features of the present invention will reside in its metallic construction such as extruded aluminum or the like which is long lasting, rigid in construction, easy to install, easy to operate and maintain, substantially burglar proof and generally inexpensive to manufacture.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 12 is an elevational view of one of the window panels illustrating the construction thereof.

Referring now specifically to the drawings, the numeral 10 generally designates the metal window construction of the present invention of the double hung type including a lower sash generally designated by the numeral 12 and an upper sash generally designated by the numeral 14 and also an upper storm panel 16 and a lower storm panel 18 and a single screen panel 21}. The storm panels 16 and 18 are immovable once they are installed but are removable for cleaning and storage. The sashes 14 and 12 are vertically movable in the normal manner of a double hung window.

The window is provided with an external frame including side members or rails 22 each of which is constructed of an outwardly facing channel shaped member. The frame is also provided with top and bottom rails 24 of outwardly facing channel construction and the corners of the side rails 22 and the top and bottom rails 24 are interconnected by angle iron members 26 and connecting plates 28 on the inner face thereof. The connector plates 28 are optional and with this construction, a rigid frame will be provided with the peripheral channel forming means for receiving therein the adjacent wall structure designated by reference numeral 30. The various components of the window are preferably extruded aluminum and a plurality of the window units may be attached in side-by-side relation to provide a multiple window unit when desired and the dimensions of the window may be varied for adapting the window to various installations.

Each of the sashes 12 and 14 are slidingly guided by a vertically disposed track 32 rigid with each side rail 22. Each track 32 includes a cylindrical bore 34 having a groove 36 facing inwardly communicating with the bore. Thus, a track is formed in which the internal surface is cylindrical in shape with the internal surface extending for more than one-half of a cylinder. The tracks 32 extend throughout the length of the side rails 22 for guiding the movement of the upper and lower sashes 14 and 12.

Each of the sashes 12 and 14 includes a peripheral frame rail 38 of inwardly facing channel shaped construction with the outer surface of the side rails of the sash frame including a longitudinally extending projection 40 which is cylindrical in shape and joined to the frame rail 38 by a reduced portion 42 which is slidingly received in the groove 36 with the cylindrical projection 40 being received slidably in the cylindrical bore or recess 34. The cylindrical projection 48 is hollow and the end edges thereof are split as indicated by reference numeral 44 and the split end portions receive a spreading screw 46 which, when screwed inwardly will expand the ends of the cylindrical projections 40 thereby adjusting the degree of frictional engagement between the cylindrical projection 40 and the cylindrical recess or bore 34 whereby the sashes will be retained frictionally in their adjusted position.

The upper and lower part of the track for receiving the window sashes is in the form of an inwardly facing channel shaped member 48 which telescopically engages the end edges of the sash frame rail 38 when the sashes are raised and lowered. The lower end rail of the sash frame is of hollow box construction as indicated by the numeral 50 while the upper rail is also of hollow box construction indicated by the numeral 52. Each of the window sashes is provided with a glass pane or panel 54 engaging a peripheral flange 56 on one surface thereof and having a sealing or glazing strip 58 interposed between the glass panel 54 and a flange 60 on the other surface thereof. Each sash may also be provided with a double pane construction as described hereinafter in connection with one of these storm panels.

For retaining the upper and lower sashes 14 and 12 in locked enclosed position, a lock mechanism is provided that includes a rotatable generally circular plate 62 mounted on a vertical pin 64 and disposed within a recess 66 in the upper rail 52 of the lower sash 12. The external surface of the plate 62 is knurled as at 68 or is provided with a handle for rotation of the circular plate 62. A portion of the periphery of the plate 62 is provided with a cam groove or slot 70 therein for locking engagement with a vertical pin 72 disposed within a recess or groove 74 in the bottom rail 50 of the top sash 14. In one position of the locking plate 62, the plate 62 will be completely disengaged from the upper sash and retained completely within the confines of the upper rail of the lower sash thereby permitting sliding relative movement between the upper and lower sashes. When the upper and lower sashes are in their extended positions, they may be locked in this position by rotating the plate 62 in the direction of the arrow illustrated in FIGURE 8 for registering the groove or slot 70 with the locking pin 72 which will effectively lock the sash members 12 and 14 in their extended position. The groove or slot may be in the form of a cam for urging the adjacent edges of the sashes towards each other and otherwise forming a more effective seal for the sashes and their tracks.

Each glass panel 54 has a frame defined by the flanges 56 and 60 that are connected to an outwardly facing channel shaped member 76 and is locked in the frame defined by rails 38, 50 and 52 by virtue of a pair of swingable lock pins 78 carried by rotatable studs 80 journaled in the hollow box rail 38 with one end thereof being provided with a screw slot 82 for receiving a screwdriver or other suitable instrument for rotating the stud 80 about its axis for swinging the pin 78 through a slot into engagement with the outwardly facing channel shaped member 76 thereby retaining the panels in position. Also, each panel defined by the glass pane 54 and the frame member 76 is provided with a pair of projecting studs along one edge thereof with the studs designated ,by the numeral 84. The studs or pins 84 form a hinge 'axis for the panels and one of the studs or pins 84 is slightly longer than the other for a purpose described hereinafter.

The pins 84 on the window panel are pivotally re ceived in slots 86 in the side rail 38 adjacent the bottom thereof which provides for pivotal movement of the win- 'dow panels and also removal of the window panels. The upper window panel in the upper sash 14 has one pin received in the slot 86 and the other pin is received in an aperture in the opposite side rail 38. Thus, by taking the side edge of the window panel when in the condition illustrated in FIGURE 9 and lifting it up in the slot 86, pivotal movement of the window panel will cause the pin 84 to move out of the slot 86 in an arcuate upward swinging manner whereby the other end may then be retracted from the aperture in the opposite side rail 38.

In the bottom sash, the bottom rail 50 is also provided with a slot 88 and the top rail 52 is provided with a corresponding aperture for receiving the two pins 84. The side rail 38 of the bottom sash has a slot 86 similar to the slot 88 and at the lower corner thereof. The side rail 38 opposite to the slotted side rail is provided with an aperture. This provides for swinging movement of the lower window panel about a vertical axis as illustrated in FIGURE 9 or about a horizontal axis in which the window panel in the lower sash would be mounted in the same manner as the window panel in the upper sash.

For releasably retaining the pins 84 in the respective slots 86 and 88, there is provided a retaining clip generally designated by the numeral 90 which includes a small plate 92 having a notch 94 in the lower end thereof forming a pair of spaced legs 96 for bridging the pin 84. The plate member lies along the surface of the frame rail of the window pane frame and includes a laterally extending lug 98 at the upper end thereof and a longitudinal extension 100 which is in the same plane as the plate 92. The laterally extending lug 98 is spaced from the bottom of the notch 94 in such a manner that the lug 98 will be. disposed within the upper end of the slot 86 and the extension 100 along with the plate 92 will be disposed alongside the inner surface of the frame rail 38 as illustrated in FIGURE 10. The orientation of the legs 96 between the side rail 38 and the frame 76 of the window pane will retain the clip 90 in position until the clip 90 is flexed outwardly slightly to retract the lug 98 from the slot 86 thereby permitting the clip 90 to be removed thereby enabling the window panel to be removed as described previously.

Adjacent the rear edge of each frame rail 22 for the window is an L-shaped hanger 102 having a horizontally extending U-shaped trough 104 therein for receiving the projecting pins 106 on the screen panel 20 or on one of the storm window panels 16 or 18 for permitting storage of either the screen or one of the storm window panels. The screen 20 includes a panel of screen mesh 108 and a frame member 110 having the pins 106 at each edge thereof. Rearwardly of the L-shaped bracket there is provided a pair of hollow side rails 112 rigidly aflixed to the side rails 22 and a seal member 114 is disposed against the rear of the rail 112 and extends beyond the edge of the rail 112 and is held in position by a retaining plate 116 whereby the seal 114 will effectively engage the channel shaped frame 118 of the storm panels 16 or 18. The upper storm panel 16 is provided with pins 120 extending laterally therefrom at each corner. The upper pins are received in notches 122 cut into the upper end of the side rail 112. The pins on the lower corner of the upper storm panel is received in notches 124 adjacent the center of the side rail 112. The lower storm panel 18 is also provided with laterally projecting pins on the upper end thereof which are comparable to the pins 120' and these pins also are received in the notch 124. The lower edge of the bottom panel 18 rests on a sealing member 126 setting on a bottom rail 128, thereby forming an effective seal for the lower edge of the lower storm panel. The upper storm panel rests on the top edge of the lower storm panel with the pin 120 resting in the notch 122 which may be considered a reentrant notch in that the pin 120 drops down in a cut-away recess 130 when it is inserted into the notch 122. The notch 124 is provided with a sliding closure plate 132 having a screw threaded member 134 connected thereto extending through a slot 136 in the rail 112 in which the plate 132 may be blocked in closing relation to the slot 124 or in relation for opening the slot 124. The edge of the frame rail 112 facing the window panels is also slotted so that the pin 129 on the top of the bottom storm panel 18 may be inserted through the slot 124 and then dropped into the notch 138 after which the pin 120 on the lower end of the upper storm panel 16 may be inserted through the notch 124 and .after the upper pin 120 has been inserted through the recess 130, the entire top panel is moved downwardly until the pin 120 at the bottom of the storm window rests against the pin on the lower panel and the two panels actually are in abutting engagement. In this condition, the upper pin 120 on the upper end of the upper storm panel 16 is disposed in the notch 130. The closure plate 132 may then be moved downwardly and locked in position by the screw threaded fastener 134 thereby preventing removal of the storm window panels 16 and 18 after they have been installed until such time as the screw 134 is released and the plate 132 elevated to its open position. With this structure, it is substantially impossible to remove the storm panels from the outside unless the storm panels are broken. Even then, it is extremely difficult to remove the storm panels since the screw threaded member -is facing and is closely adjacent to the upper double hung sash panel 14.

All four of the window panels may be of double pane construction and this is accomplished by merely adding a second panel of glass 140 in overlying relation to the usual panel of glass 142 such as is employed in the storm window panels. The usual panel of glass 142 is provided with a sealing member 144 on the inner surface thereof and the second panel of glass 140 is merely disposed against the sealing material 144. Against the surface of the panel 140 remote from the sealing material 144, another strip of sealing material 146 is provided and in overlying plate 148 is disposed peripherally of the panel 140 and the sealing material 146 .and secured to the frame 118 in the storm window panel 16 as illustrated in FIGURE 4. However, the additional pane of glass 140 may be added to either the storm window panels, the double hung sash panels or both thereby providing a high degree of insulation since the dead air space between the glass panels will provide insulation.

The entire hollow frame rail assembly may be filled with an insulation material such as foam rubber or the like in which the hollow rails are filled by having the material blown into them through a suitable aperture or apertures. If this is done, the various openings, slots and the like in the frame rails must be provided with covers spaced from the interior edge thereof to prevent exit of the insulation material.

The alternate means of mounting the inner panels may be employed in both the top and the bottom since in some instances it is desirable to swing the window panel downwardly for ease of cleaning and removal and in other instances it may be desirable to swing the panel from the side edge thereof. This will depend upon the installation of the window and other factors including the desires of the person installing the window. The arrangement provides a substantial seal for the entire window in that the engagement of the storm panels with the seal performs one v 6 sealing operation and the engagement of the double hung sashes with the tracks forms another seal.

Additionally, it is pointed out that the window lock may have other utility in that it can be used for doors and the like and the method of conversion from a single pane to a double pane glass may be employed in other types of windows. The particular construction of the device from structural hollow elements, channels and the like provides rigidity as does the corner angle iron and generally, the window will be rigid, long lasting and still relatively inexpensive to manufacture and easy to install. While the framing elements are disclosed as being constructed of extruded aluminum, it is also Within the purview of this invention to employ other metals, rigid plastics, synthetics, wood and the like in the construction of the Window. In view of the rigidity of the framing and the insulation features built into the window, this window can easly be employed in new buildings having walls substantially of glass.

The foregoing is considered as illustrative only of the principles of the invention.
